Date: Sun, 17 Feb 2013 14:33:04 +0100 From: Jiri Slaby <jslaby@...e.cz> To: tiwai@...e.de Cc: perex@...ex.cz, jirislaby@...il.com, linux-kernel@...r.kernel.org, Damien Zammit <damien@...audio.com> Subject: [PATCH] sound: usb/quirks, fix out-of-bounds access bootresponse in snd_usb_mbox2_boot_quirk is only 12 (decimal) u8's long, but i9s passed to snd_usb_ctl_msg as it would be 0x12 (hexa) long. Fix that by having proper size of the array, i.e. 0x12.
